SHOCK ABSORBER.

Application filed July 20, 1822. Serial No. 576,304.

To all whom it may concern: of my invention for use on the well known Be it known that l, VILLIAM P. COLE, a Chevrolet automobile, and citizen of the United States, residing at Figure (3 is a sectional view taken on line Coalinga, in the county of Fresno and State 6 6 of Figure 5.

In Figure 1, I have shown a slightly modified form, wherein the hanger 3, instead of being secured to the axle 1 is made fast to the frame orv rear hub plate of thccar 2, otherwise, the construction of the shock absorber is the same as described in Figures 1 and 2.

In Figure 5, I have shown a further modified form, and particularly adapted for use on the Chevroletautomobile. In this instance, instead of having the spring 2 run parallel with the axle 1, same is at right angles to the latter, and while one end of the leaf spring is supported by the axle to means already described, the opposite end of the leaf spring is attached to the body of the motor vehicle. A brace rod 20 having a hinged joint 21 is secured at its opposite ends to the front andrear axle of the motor vehicle.

In view of the foregoing description or my invention taken in connection with the accompanying drawings, it is thought that any further enplanation as to the construc tion, operation, and objects of same are unnecessary.

\Vhile I have shown and described the preferred form of my invention, I realize that various minor changes may be resorted to, without departing from the spirit and scope of the appended claims, and therefore, I do not wish to limit myself to the exact details of construction shown, nor tothe combination and arrangement of parts.

\Vhatl claim as new and desire to secure by Letters Patent is:

1. In a shock absorber, the combination with an axle of a vehicle, a leaf spring, a

hanger carried by the axle and having a portion overhanging the leaf spring, a shock lever havmg one end pivotally connected to the hanger, compression springs mounted upon the leaf spring, means connecting said compression spring with the other end of the shock lever to absorb downward move 'ment of the vehicle, said leaf spring having connection withthe shockllever between its ends, and a second compression spring arranged between the shock lever and the free end of the hanger for absorbing upward movement of thevehicle;

2. In ashock absorber for motor vehicles, the combination with a vehicle axle, a leaf spring, a hanger having'its free end overhanging a portion of the leaf spring, a shock lever having one, endpivotally connected to .shoclrlever betweenits endsand the other vend of the con'ipression sprlng bearing against the, overhanging; end of the hanger,

3. In a shock absorber in combination with the axle of a motor vehicle, a leaf spring, a hanger, a shock lever pivotally connected to said hanger, ,means for connecting saidleaf springto said shock lever,

springineans connecting said shock lever ,and leaf spring for receiving the jar on downwardmovement of a vehicle-body, and

spring meanspositioned between the hanger and shock lever for receiving the rebound on upward movement of a vehicle body.

Intestimony whereof, I have aflixed my signature in the presence of two witnesses.
